There are a couple console games and one in my steam library that absolutely come to mind. As for which I think is worse is definitely up for debate because I think I dislike these 3 equally, even if I can only remember why I dislike two of them.

Don't remember the exact entry, but I borrowed a Dynasty Warrior game from my brother (who didn't like it as far as I'm aware) for xbox360 and something about it I just didn't like at all. Then there's Worms Blast. For a spin-off of worms, that from what I remember just feels like a worse bubble bobble style game, I was absolutely disappointed.

The Steam game is Macbat 64. By no means is it unplayable, add riddled, or full of annoyances preventing me from playing, but I beat it in less than 50 minutes. It's a 3D platformer whose relatively small levels pay homage to other games, but it just wasn't fun for me due to lack of content I was interested in (longer levels with more going on) when it comes to 3D platformers.
